Hello,

One more topic on this endless subject. Is'nt anyone annoyed by the 1-1..* cardinality between itinerary and Segment ?
If "Segment" has a geographical meaning, should'nt it be 1..*-1..* ?

Regards

In our case :"segment represents a single flight as booked in the system".(an official definition of segment from a recognized travel association) it has the same semantic as a lineitem in an order.
Order--->lineitem--->product
Itinerary--->segment--->flight

Hi Pierrefoids.

But a flight still has multiple legs.
Because that's the typical meaning of airline flight, right?
Take a look at flight number 96 form American Airlines:
http://dps1.travelocity.com/dparflifo.ctl?aln_name=AA&flt_num=96
I should be able to buy just the San Francisco->Boston leg. not the entire flight n� 96.
Or flight n 195:
http://dps1.travelocity.com/dparflifo.ctl?aln_name=AA&flt_num=195

What do you guys think?

Take a look at an airline ticket: usually each coupon represents a booked flight. A flight is not identified par its number only. You should give an another definition to this term.
